GAS-RANGE.

SPECIFICATION forming' part of Letters Patent No. 722,414, dated March10, 1903.

Application ned July 18,1901.

To all whom it may concern,.-

Beit known that I, GEORGE A. SIMPSON, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State of 5Pennsylvania, have invented certain new and useful Improvements inGas-Ranges; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a new and improved gas cookingstove or range; and to this end my invention consists of a new andimproved cooking stove or range, of new and improved means for heatingthe oven whereby the Walls thereof are uniformly heated, in a newarrangement of the oven burner or burners whereby the intense heatheretofore generated in gas-ranges directly over the door isdone awaywith, in a new and efficient flue system, and in the construction andcombination of parts, all as hereinafter describedV and claimed.

In the accompanying drawings, which illustrate an application of myinvention, Figure l is a perspective view of a range, showing a part ofthe front broken away to show the location of a burner and a portion ofthe oven. Fig. 2 is a vertical sectional view of the range, showing anoven-burnerin side eleration; and Fig. 3 a central vertical sectionalview taken at right angles to the view of Fig. 2.

Referring to the drawings, the casing or stove-body comprises the frontl, provided with a door 2, sides 3, and back 4, all preferably supportedon a base-plate 5. As illustrated, the interior of the stove or range isdivided into an oven 6, a broiler-space 7, in which is a burner 7 aspace 8 for the upper burners 8*, and the flues or passages, all ashereinafter described.

The oven comprises the top plate 9, the bottom plate lO, the back plate10, and the perforated side plates 11. Located between the side walls 3and the side plates 11 are detlecting-plates 12, one on each side of theoven, and between said deecting-plates and the sides of the body Iarrange the oven- For the purpose of admitting fresh air to the burners13 the base-plate is Serial No. 68,814. (No model.)

I preferably provided with a series of openings 14.

A characteristic and important feature of the present invention is themeans shown for producing an efficient and uniform heat throughout theinterior of the oven. Heretofore, so far as I am aware, the oven of agas-range has always been heated from a burner or burners locateddirectly under the bottom plate of the oven, and consequently it hasbeen impossible to heat the oven uniformly. By the construction shown Iam enabled to cause the heated air and products of combustion to travelupward from the side burners through passages 15 over the tops of thedeIiecting-plates and into the interior of the oven through openings 16of the 'side plates 11, down through the oven to a flue or passage 17,located under the oven, and from thence to a flue 18 at the back of theoven. The course of the heated air and products of combustion is.clearly indicated by the arrows. I have shown the due or passage 17having its top formed by the bottom plate 10 of the oven and the line orpassage to the rear of the oven utilizing the back plate 10a of the ovenfor one wall of the said passage. However, instead of employing thisconstruction-namely, utilizing the bottom and back oven plates for wallsof said passages 17 and l8-separate and independ-` ent plates could beemployed for the same purpose. In other words, if found desirable theselues could be formed separately from the oven and led under the bottomthereof and also up the back. Theinner face of the door 2 is employedfor the front of the oven and directs the passage of the heated air andproducts of combustion into the flue 17, as particularly shown by Fig.2. The back flue 18 continues upwardly above the oven and is incommunication with the broiler-chamber 7 by openings 19 and with theupper burnerspace 8 by the openings 20. 'lhis Hue connects with thechimney-flue (not shown) in the usual manner. Rack-holders 21 arepreferably placed directly above the openings in the side plates of theoven, and said openings are arranged to properly distribute the heatedair entering the oven therethrough.

The advantages obtained from the forni of gas cooking stove or range, asillustrated and described, will be evident to those skilled in the artto which this invention relates; but I desire to particularly callattention to the uniform heating of the interior, top, front, bottom,back, and sides of the oven; also, to the arrangement of theoven-burners Wherebythe liability of the floor on which the stove standscatching fire, as is sometimes the case under the method of manufactureof gasranges as heretofore followed, lis done away with; further, to thenew and improved flue system employed; also, to the fact that theburners are not located directly under the bottom plate of the oven, andconsequently the iames from the burners are not brought in contacttherewith, thus removing the liability of burning the articles placed inthe lower part of the oven and also prolonging the' life of said plate.

Having thus described my invention, what I claim is l l. In a gas stoveor range, the combination, with a casing, of an oven, a fine at the sideof the oven within the casing, a combustionchamber in said ue, a burnerin the combustion-chamber, a defiecting-plate between the burner andside Wall of the oven, openings in the side Wall, a flue or passageLinder the oven into which the heated air and products of combustionpass after their travel through the interior of the oven for the purposeof heating the bottom of the oven, and a flue or passage back of theoven in communication with the iiue or passage under the oven,substantially as sot forth.

2. In a gas stove or range, the combination, with a casing, of an ovenhaving a perforated side Wall and an imperforated top and bottom, aburner and a combustion-chamber in a flue at the side of the oven, aflue or passage under the oven of substantially the same Width and depthas the oven and independent of the combustion-chamber, into which theheated air and products of combustion pass after their travel throughthe interior of the oven, and a back flue or passage in communicationwith the flue or passage under the oven, substantially as set forth.

3. In a gas stove or range, the combination, with a casing, of an oven,a flue at the side of the oven Within the casing, a combustionchamber insaid flue, a burner in the combustion-chamber above the bottom plate ofthe stove, openings in a side wall of the oven for the' passage ofheated air and products of combustion from the combustion-chamber intothe interior of the oven, a flue or passage independent of thecombustion-chamber under the oven, and a flue or passage at the back ofthe oven in communication with the iiue orpassage under the oven wherebythe heated air and products of combustion have-a continuous travel fromthe combustion-chamber to the back flue or passage by way of theinterior of the oven and the iue or passage under the oven,substantially as set forth.

4. In a gas cooking stove or range, the combination, with a' casing, ofan oven having openings in the side walls thereof, a burner located ateach side-of the oven, and arranged over openings for air, and adeflecting-plate between each burner and the side walls of the oven,substantially as set forth.

5. In a gas cooking stove or range, the comb'ination, with a casing, ofan oven, a ue at the side of the oven, a burner therein, openings in aside Wall of the oven for the passage of heated air and products ofcombustion from the side flue to the interior of the oven, a flue orpassage under the oven, a back flue or passage in communication with theflue or passage under the oven, a broiler-chamber having a burnertherein above the oven and in communication with the back fine orpassage, substantially as set forth'.

6. In a gas cooking stove or range, the combination, with a casing, ofan oven, a ue at the side of the oven, a burner in said side ue,openings in a side wall of the oven for the passage of heated air andproducts of combustion from the side flue to the interior of the oven, aflue or passage under the oven, a back iiue or passage in communicationwith the flue or passage under the oven, a burnerchamber above the ovenin communication with the back Hue, and a burner in said chamber,substantially as set forth.

In testimony whereof I aix my signature in presence of tWo witnesses.
